Abstract: The invention belongs to the field of mineral flotation collector materials, and particularly discloses a method for preparing thionocarbamate. In the preparation process, xanthate and 2-haloethanol are esterified to obtain O-alkyl-S-hydroxyethyl xanthate, and then O-alkyl-S-hydroxyethyl xanthate and fatty amine are reacted to obtain a mixture of thionocarbamate and 2-mercaptoethanol. The mixture of thionocarbamate and 2-mercaptoethanol is washed with alkali, and the oil phase and water phase are separated. The oil phase and water phase are thionocarbamate and 2-hydroxyethylthiolate, respectively, and 2-mercaptoethanol is obtained by washing with an acid. 2-alkylthioethanol is obtained by reacting 2-hydroxyethanethiolate with alkyl halide, and then with carbon disulfide and alkali to prepare O-alkylthioethyl xanthate. Thionocarbamate, 2-mercaptoethanol and O-alkylthioethyl xanthate prepared by this method possess high yield and high purity.

Abstract: Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.

Abstract: The present invention provides a cleaning cup for coffee machine and a coffee machine. The cleaning cup comprises a main cup body, a water injection assembly, at least a liquid-discharging hole group, and a liquid-discharging tube. When the cleaning cup is fittingly arranged on the extracting parts of the coffee machine, the water injection assembly injects liquid into the main cup body to mix with a detergent within the cup body. The detergent rapidly dissolves in water to form a washing liquid, and the washing liquid is conveyed to the gaps between the extracting parts of the coffee machine through the liquid-discharging hole group and the liquid-discharging tube, thereby flushing away residual coffee grounds and coffee stains. The present invention has advantages of simple to use, convenient operations, easy promotions and implementations.

Abstract: A multi-dimensional adjustable forklift driving system includes a cab in which a steering wheel control system, a base plate control system and a pedal system are provided; where the steering wheel control system includes a steering wheel diverter and a first telescopic adjustment device, which is connected to the steering wheel diverter to drive the steering wheel diverter to move; the base plate control system includes a base plate assembly and a second telescopic adjustment device connected to the base plate assembly to drive the base plate assembly to move up and down; the pedal system includes a pedal body and a third telescopic adjustment device connected to the pedal body to drive the pedal body to move.

Abstract: This application provides an apnea monitoring method and apparatus, and relates to the field of medical monitoring. The apnea monitoring method includes: collecting a first sound of at least one user by using a first terminal, where first sounds corresponding to users in coverage areas of different beams are determined by using directional beam forming of a multi-microphone array configured on the first terminal, or first sounds of different users are distinguished from each other by using a voiceprint recognition algorithm; obtaining a power spectrum density corresponding to the first sound based on the first sound; and when the power spectrum density is less than a first threshold, determining that the user encounters apnea. According to the apnea monitoring method provided in this application, apnea monitoring for one or more users can be implemented without one or more users having to wear a monitoring instrument.
